Effects of graphene oxide (GO) on various properties of rubber hybrid nanocomposites based on PVMQ/XNBR-g-GMA/XNBR (phenyl-vinyl-methyl-polysiloxane/carboxylated nitrile rubber-grafted maleic anhydride/XNBR) were identified. These nanocomposites were prepared with melt mixing method and fabricated by a laboratory two-roll mill. To evaluate the adhesion between the blend phases, i.e., PVMQ and XNBR, the results of microscopic and swelling tests were used simultaneously. The results showed that the adhesion of GO on PVMQ/XNBR rubber matrix was increased by the incorporation of XNBR-g-GMA as a compatibilizer. By increasing the amount of GO in the blend to 10 phr, the scorch time and curing time decreased by 24% and 26%, respectively, while the curing rate and maximum curing torque increased by 27% and 15%, respectively. Tear strength, hardness, and compression set of samples increased with increasing the GO content. The SEM images showed that the porosity of the prepared nanocomposites decreased from 17.34 to 4.84 µm for 5 phr GO. In the presence of a compatibilizer, the size of XNBR dispersed phase declined. This means that a stronger bond is formed between the blend phases. The results of TEM images also illustrated that the addition of compatibilizer to the PVMQ/XNBR rubber matrix resulted in excellent dispersion of GO nanoplatelets. To predict the mechanical and rheological properties, Mooney–Rivlin and Carreau–Yasuda models were applied, respectively. The parameters of these models were theoretically determined and compared with the experimental data, and a good agreement was observed.

确定了氧化石墨烯 (GO) 对基于PVMQ/XNBR- g- GMA/XNBR（苯基-乙烯基-甲基-聚硅氧烷/羧化丁腈橡胶接枝马来酸酐/XNBR）的橡胶杂化纳米复合材料的各种性能的影响。这些纳米复合材料采用熔融混合法制备，并由实验室两辊轧机制造。为了评估共混相之间的粘合力，即 PVMQ 和 XNBR，同时使用显微和溶胀试验的结果。结果表明, GO 在 PVMQ/XNBR 橡胶基体上的附着力因 XNBR- g的掺入而增加-GMA 作为增容剂。通过将共混物中 GO 的量增加到 10 phr，焦烧时间和固化时间分别减少了 24% 和 26%，而固化速率和最大固化扭矩分别增加了 27% 和 15%。样品的撕裂强度、硬度和压缩永久变形随着 GO 含量的增加而增加。SEM 图像显示，对于 5 phr GO，所制备的纳米复合材料的孔隙率从 17.34 µm 降低到 4.84 µm。在增容剂的存在下，XNBR 分散相的尺寸下降。这意味着在混合相之间形成了更强的键。TEM 图像的结果还表明，在 PVMQ/XNBR 橡胶基质中添加增容剂导致 GO 纳米片的良好分散。为了预测机械和流变特性，分别应用了 Mooney-Rivlin 和 Carreau-Yasuda 模型。对这些模型的参数进行了理论确定并与实验数据进行了比较，观察到了良好的一致性。
